Associating Member Profiles

I’m no stranger to WordPress but Buddypress is somewhat new territory for me. At this time, I’m developing a community site. Below I’ve listed the versions
wp v3.5.1
bp 1.7.1 (theme compatibility)
theme framework is Genesis v1.9.2
dev url: http://creativeconundrum.com/kristen2

My client is “emotionally prepared” to have to set up individual profiles separately but she would like to have the ability to associate profiles of family members within a member’s profile. BP-Xprofiles extends the fields that I can create but my puzzle is how to actually create an extended profile field that will permit members to select other members who are family members.

I found this forum link that looks as though it would provide a method of producing this list for selection:

As was noted in the thread that led me to the above link, there is very little documentation available on this brand new feature.

I’ve written many sites that leverage custom post types and I can imagine that this would allow a user to enter their family member profile links. Presenting this additional content to the single member profile output, would work but it isn’t as elegant as I was hoping for.

I hope this doesn’t sound stupid, but I’m new to BuddyPress and Woocommerce. I have 3 levels of members at my site. How do I create different levels of members in BuddyPress? I’m also confused as to setting up the General Settings for Subscribers. What do I set it to to connect the member profile to the Woocommerce when a purchase is made. Hope I’m making this clear.
